Estimate your ideal weight range using the classic Robinson formula.
An ideal weight is not a single fixed number. For women, healthy weight depends on skeletal frame, height, body composition, and age. A woman with a small frame and one with a larger frame can both be healthy at noticeably different weights for the same height. This is why the Robinson formula and similar clinical equations offer a range rather than an absolute target.
Traditional BMI is a useful population screening tool, but it cannot distinguish muscle from fat, nor account for frame size or fat distribution. A "normal" BMI does not automatically mean healthy, and a slightly high BMI is not necessarily a health risk. Ideal weight should be read alongside body composition, waist circumference, and overall lifestyle. Because health data is personal, this calculator runs 100% client-side in your browser — nothing is uploaded or stored on a server, so your measurements stay private on your own device.
